Who made these? I have a Q? into Forster.

They take a 1/4 bit but I don't see any tooling out there for it.

I think it's home made.

Might have been Herters. I have one of their old trimming tools that is similar, but only one piece like the forster.

Herters makes sense since pop had their dies and a press. Hadn't thought of that.

bits are 1/4" - most company's stuff is threaded 8x32 (.164)
